就是這樣！ 您剛剛在 C# 中創建了您的第一個 PDF。不需要學習複雜的 PDF API，不需要安裝服務器依賴項，不需要掌握低級的 PDF 命令。只需輸入 HTML，輸出 PDF - 這才是 PDF 生成的正確方式。但這僅僅是開始 - 讓我們探討為何這種方法如此強大以及如何創建更精細的 PDF 文件。

如何在 C# 中創建 PDF：快速概覽

要在 C# 中創建 PDF，您可以使用第三方庫，如 IronPDF、QuestPDF 或 PDFsharp。這些庫提供多種功能，包括從頭開始創建 PDF、將 HTML 轉換為 PDF 等。

這是此過程的一般概述：

安裝 PDF 庫：使用 Visual Studio 中的 NuGet 程序包管理器安裝合適的庫。
創建新的 PDF 文件：實例化一個 PDF 文檔對象。
添加內容：為文檔添加頁面、文本、圖像和其他元素。
保存文件：指定文件路徑並保存 PDF。

這是使用IronPDF的一個例子：

using IronPdf;

public class Example
{
    public static void CreatePdf()
    {
        // Create a new PDF document
        var pdf = new ChromePdfRenderer();

        // Add some text
        string htmlContent = "<h1>Hello, PDF!</h1><p>This is a dynamically created PDF.</p>";

        // Render HTML to PDF
        var pdfDocument = pdf.RenderHtmlAsPdf(htmlContent);

        // Save the PDF
        pdfDocument.SaveAs("MyDynamicPdf.pdf");
    }
}

using IronPdf;

public class Example
{
    public static void CreatePdf()
    {
        // Create a new PDF document
        var pdf = new ChromePdfRenderer();

        // Add some text
        string htmlContent = "<h1>Hello, PDF!</h1><p>This is a dynamically created PDF.</p>";

        // Render HTML to PDF
        var pdfDocument = pdf.RenderHtmlAsPdf(htmlContent);

        // Save the PDF
        pdfDocument.SaveAs("MyDynamicPdf.pdf");
    }
}

Imports IronPdf

Public Class Example
	Public Shared Sub CreatePdf()
		' Create a new PDF document
		Dim pdf = New ChromePdfRenderer()

		' Add some text
		Dim htmlContent As String = "<h1>Hello, PDF!</h1><p>This is a dynamically created PDF.</p>"

		' Render HTML to PDF
		Dim pdfDocument = pdf.RenderHtmlAsPdf(htmlContent)

		' Save the PDF
		pdfDocument.SaveAs("MyDynamicPdf.pdf")
	End Sub
End Class

最常見的問題之一是 PDF 顯示為空白或無法正確渲染。

這通常發生在資產未及時加載或有JavaScript 時序問題時：對於持續渲染問題，啟用日誌記錄以診斷問題：

// Namespace: IronPdf using IronPdf; // Namespace: System.IO using System.IO; // Namespace: System using System; // Problem: PDF is blank or missing content var renderer = new ChromePdfRenderer(); var pdf = renderer.RenderHtmlAsPdf(complexHtml); // Results in blank PDF // Solution 1: Add render delay for JavaScript-heavy content renderer.RenderingOptions.RenderDelay = 3000; // Wait 3 seconds renderer.RenderingOptions.EnableJavaScript = true; // Solution 2: Wait for specific elements renderer.RenderingOptions.WaitFor = new WaitFor() { JavaScriptQuery = "document.querySelector('#chart-loaded') !== null", WaitForType = WaitForType.JavaScript, Timeout = 30000 // 30 second timeout }; // Solution 3: Use base path for local assets var basePath = Path.GetFullPath("Assets"); var pdf = renderer.RenderHtmlAsPdf(htmlWithImages, basePath); // Solution 4: Embed assets as Base64 var imageBase64 = Convert.ToBase64String(File.ReadAllBytes("logo.png")); var htmlWithEmbedded = $@"<img src='data:image/png;base64,{imageBase64}' />";

// Namespace: IronPdf using IronPdf; // Namespace: System.IO using System.IO; // Namespace: System using System; // Problem: PDF is blank or missing content var renderer = new ChromePdfRenderer(); var pdf = renderer.RenderHtmlAsPdf(complexHtml); // Results in blank PDF // Solution 1: Add render delay for JavaScript-heavy content renderer.RenderingOptions.RenderDelay = 3000; // Wait 3 seconds renderer.RenderingOptions.EnableJavaScript = true; // Solution 2: Wait for specific elements renderer.RenderingOptions.WaitFor = new WaitFor() { JavaScriptQuery = "document.querySelector('#chart-loaded') !== null", WaitForType = WaitForType.JavaScript, Timeout = 30000 // 30 second timeout }; // Solution 3: Use base path for local assets var basePath = Path.GetFullPath("Assets"); var pdf = renderer.RenderHtmlAsPdf(htmlWithImages, basePath); // Solution 4: Embed assets as Base64 var imageBase64 = Convert.ToBase64String(File.ReadAllBytes("logo.png")); var htmlWithEmbedded = $@"<img src='data:image/png;base64,{imageBase64}' />";

' Namespace: IronPdf Imports IronPdf ' Namespace: System.IO Imports System.IO ' Namespace: System Imports System ' Problem: PDF is blank or missing content Private renderer = New ChromePdfRenderer() Private pdf = renderer.RenderHtmlAsPdf(complexHtml) ' Results in blank PDF ' Solution 1: Add render delay for JavaScript-heavy content renderer.RenderingOptions.RenderDelay = 3000 ' Wait 3 seconds renderer.RenderingOptions.EnableJavaScript = True ' Solution 2: Wait for specific elements renderer.RenderingOptions.WaitFor = New WaitFor() With { .JavaScriptQuery = "document.querySelector('#chart-loaded') !== null", .WaitForType = WaitForType.JavaScript, .Timeout = 30000 } ' Solution 3: Use base path for local assets Dim basePath = Path.GetFullPath("Assets") Dim pdf = renderer.RenderHtmlAsPdf(htmlWithImages, basePath) ' Solution 4: Embed assets as Base64 Dim imageBase64 = Convert.ToBase64String(File.ReadAllBytes("logo.png")) Dim htmlWithEmbedded = $"<img src='data:image/png;base64,{imageBase64}' />"

詳細比較

IronPDFvs wkhtmltopdf

-wkhtmltopdfis free but was abandoned in 2020 and produces dated-looking PDFs

需要平台專用的可執行文件，部署更為繁瑣 -否JavaScript support means modern web apps won't render correctly -IronPDFoffers modern rendering with no external dependencies

IronPDFvs QuestPDF

-QuestPDFrequires building PDFs entirely in C# code with no HTML support -好for programmatic PDF creation but time-consuming for complex layouts

Recently switched fromMITto commercial licensing -IronPDFlets you use HTML/CSS skills you already have

IronPDFvs iText 7

iText 使用的 AGPL 許可可能會 "傳染" 您的代碼 -商業licenses start at $1,999 with complex pricing -有限HTML to PDF capabilities with poor CSS support -IronPDFprovides superior HTML rendering at a lower price point

IronPDFvs PdfSharp

-PdfSharpis great for low-level PDF manipulation but has zero HTML support

需手動定位頁面上的每個元素 -免費and open source but very limited in features -IronPDFhandles both high-level HTML and low-level PDF operations

IronPDFvs Syncfusion/Aspose.PDF

兩者均為企業級方案，功能豐富但價格較高 -Syncfusionstarts at $2,995, Aspose at $2,499

兩者均未能實現 IronPDF 的像素完美 HTML 渲染 -IronPDFoffers better value with comparable enterprise features

遷移路徑

Many developers switch toIronPDFfrom other libraries. 原因如下：

從 wkhtmltopdf

"我們對處理平台特定的二進制文件和過時的渲染已經厭倦了"

"IronPDF 提供了現代化的 CSS 支持並且消除了我們的 Docker 頭痛"

從 iTextSharp/iText 7

"The learning curve was killing our productivity -IronPDFlet us use HTML instead"

"AGPL 許可對我們的商業產品是一個攔路虎"

從 PdfSharp

"We needed HTML to PDF conversion, whichPdfSharpsimply doesn't do"

"手動定位每個元素耗費時間"

從 QuestPDF

"在 C# 代碼中製作佈局比用 HTML/CSS 繁瑣"

"最近的許可變更讓我們重新考慮我們的選擇"
